To all whom itma z concern:

Be 'it' known that I, WILLIAM GOULD, a citizen of theflUnited States, residing at Austin; in thecounty of Grant and State of Oregon, have invented new and useful Improvements in'Bolts, of which the following; is a-specifioation.

- tPhisj invention relates .to bolts and has a V for: its-chief objectto provide a bolt which nhlyfhe 'inserted head first through the bolt hoe in-a metal plate or the like object, and

- which is adapted especially for use in boiler constructions or other places wherein it is inconvenient or impossible to insert the bolt through the opening in the usual manner, 1 such as in a case where oneof a pair" of narrowly spaced members is provided with s an opening for the reception of a bolt which.

head portions of the split sections will have a maximum area of engaging surface.

Another object is the p ovision in a bolt of this character of a spacnl member which -has its exterior faces threaded so 'that the nut for the bolt will serve to secure the said member against longitudinal movement with respect to the split sections,

The invention consists in the features of construction, combination and arrangement of parts, hereinafter fully described and r claimed, reference being bad to the accompanying drawing, in which: I I Figure 1 is a side elevationof the bolt showing itsparts assembled; Fig. 2 is a front elevation of the head of the olt; Fi 3 is a. transverse sectional view of the shan of the same; .Fig. 4 is a longitudinal sectional view. through the bolt and a member to which the same is applied; Fig. 5 is a transverse sectional view through a perforated member showing one section of the v bolt in side elevationduring the act of inair of longitudinally split sec-.

.sertingits head ,portio ithrough ithe bolt hole; and, Fig. 6 is ,afsimilar view showing the first section in applied position'andthe coacting section in theact-of insertingits head portion through the unobstructed por- .tion of the bolt hole.

In the drawing, the numeral 1 designates the bolt which is split longitudinally to provide the companion sections 2 and 31 The section 2 ispmyided upon one'end thereof with an enlargedhead portion 4 which pro.- ]e.cts laterally therefmmand is constructed just thick: enough its insertion through a bolt hole such-asi-that indicated -by the numeral, 5 in the member .6, which?) may represent a boarder metal-platawitbout binding therein. In erdesto facilitate this insertion, as is shown in Fig. 5,-the ofiter side face of the head portion of this bolt section is constructed convex and the? inner face of the bolt section as a whole is constructed slightly convex also. The come; panion section 3 is provided with an enlarge ment 7 on one'end thereof which projects laterally to form a head portion of less thickness than the head ortion of the section 2 so that it may be inserted with com parative ease through the unobstructed portion of the bolt hole 5 after the first-named section has been completely app ied within the sand hole, as is shown particularly in Fig. 6. The bolt section 3 has th outer side face of its portion 7 formed convex, as well SO that, the insertion of the boltinto apas the inner face of this section as a whole, l

lied position within the bolt hole'may. be

acilitated, and also for afurtherfpurpose which will presently described.

A spacing1 member 8 equal in width and length to t e bolt sections previously described is adapted to be inserted longitudinallv between the said bolt sections, after the application-of the same within the bolt hole has been completed, the opposite, wide faces of the s acing member being constructed concave or even engagementwith the adjacent-convex faces of the'bolt sections, this "arrangement of faces serving to prevent lat-.

eral displacement of the spacing member, after its initial application. The end por ,tion of the bolt, as a. whole, opposite to its composite head, is externally screw'thread-- ed as at 9, these threads being formed in" the spacing member likewise, so that longitudinal movement of the latter, with respect to the companionbolt sections, will be preing longitudinally split sections including 15 j vented after a suitable nut (not shown) has threaded shank portions and oppositely pro- .been applied thereto. jecting, alined head portions, and a spacing From the foregoing description, taken in member adapted to be inserted between the 5 connection with the accompanying drawing, said sections, the adjacent faces of the reit should be apparent that I have provided spect-ive bolt sections and spacing memberzo a simply constructed and readily operable being oppositely curved. bolt which will be of maximum strength and In testini ony whereof I afiix my signadillarability, anal which Will be a tim; and ture in presence of two witnesses; l 10 la or savin evice when used in t e capacity for w hich itjis intended.
